4.26 <strong>Numerical</strong> domain <strong>of</strong> the frequency-dispersive model. The<br />
numbers 2.07, 4.47 and 8.00 express the radii in meters <strong>of</strong> the<br />
undisturbed shoreline <strong>of</strong> the island base at the tank bottom<br />
and <strong>of</strong> the external circular boundary respectively . . . . . . . 72<br />
4.27 Comparison <strong>of</strong> the free surface elevations at the near field<br />
gauges position, measured (red dashed line) and obtained<br />
from the numerical model (black solid line). The numerical<br />
results are achieved by using the registration <strong>of</strong> the free surface<br />
elevation at the gauge 15S to estimate the wave source term. . 74<br />
4.28 Comparison <strong>of</strong> the free surface elevations at the far field gauges<br />
position, measured (red dashed line) and obtained from the<br />
numerical model (black solid line). The numerical results are<br />
achieved by using the registration <strong>of</strong> the free surface elevation<br />
at the gauge 15S to estimate the wave source term. . . . . . . 75<br />
4.29 Comparison <strong>of</strong> the free surface elevations at the back field<br />
gauges position, measured (red dashed line) and obtained<br />
from the numerical model (black solid line). The numerical<br />
results are achieved by using the registration <strong>of</strong> the free surface<br />
elevation at the gauge 15S to estimate the wave source term. . 76<br />
4.30 Comparison <strong>of</strong> the wave energy spectra at gauges 12S (left<br />
panel) and 15S (right panel), measured (red dashed line) and<br />
obtained from the numerical model (black solid line). The<br />
numerical results are achieved by using the registration <strong>of</strong> the<br />
free surface elevation at the gauge 15S to estimate the wave<br />
source term. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 76<br />
